Hello, Scribe. It is sadly a wide-spread issue that affects many players' experience while doing their dragon hunt. However, since this is hard to prove (leeching is illegal according to the game abuse policy, although I'm not sure if it's limited to pvp) it'd be more useful if you reported it directly to https://exchange.che...s.com/messenger including screenshots, videos or any other sort of proof.

If you want to avoid this sort of problems, however, remember you can always leave a dragon hunt without any sort of penalty and join a different one so the person who is trying to get carried actually has to do something to get his rewards (or be left afk without even noticing). Also, some AFK players in early stages of DH are often AFK during the queue and might not notice the game has already begun be patient and try to wait for a minute or two before getting nervous.
